Electronic apparatus

Abstract

An electronic apparatus includes a CPU provided in a first chassis and generating heat, a plate-shaped vapor chamber provided in the first chassis and thermally connected to the CPU to radiate heat, and two heat pipes protruding and extending from the vapor chamber at positions separated from each other. A graphite sheet that is thinner than the vapor chamber is thermally connected to the two heat pipes. A battery device having three cells is provided in the first chassis, and the heat pipe extends into a groove portion formed between the cells.
